Number in the figure: 1 first action bars, 2 second action bars, 3 wire clamp, 4 insulated handles, 5 earth connection connecting clips; 6 cylindrical slide bars, 7 oval rotating shafts, disk on 8,9 lower discs, 10 circular grooves; 11 cutting ferrules, 12 is protruding, 13 ribs, 14 earth brace casees, 15 insulation protective jackets.
Below by way of embodiment, and the invention will be further described by reference to the accompanying drawings.
Embodiment:
Embodiment: by reference to the accompanying drawings, the case dress portable telescopic ground operation bar of the present embodiment, it comprises insulating bar, insulated handle 4 and wire clamp 3, wherein, insulating bar is made up of the first action bars 1 of hollow and the second action bars 2, wire clamp 3 is fixedly connected on the upper end of the first action bars 1, and insulated handle 4 is fixedly connected on the bottom of the second action bars 2, and wire clamp 3 is fixedly connected with earth connection connecting clip 5.
In order to realize the flexible of insulating bar and locking: the lower end of the first action bars 1 is inserted in the inner chamber of the second action bars 2 and can slides up and down and be locked by lockable mechanism, and this lockable mechanism comprises:
Be fixedly connected on the cylindrical slide bar 6 of the first action bars bottom, being provided with cross section in the bottom integral type of slide bar is oval oval rotating shaft 7, oval rotating shaft 7 is arranged with slide bar 6 axiality, disk 8 lower disc 9 is provided with on the top of oval rotating shaft and bottom integral type, namely upper disk 8 is the bottom surface of slide bar, the card of lower disc is vertical with oval shaft axis, twice circular groove 1 is provided with separately at the end face of the bottom surface of upper disk and lower disc), the twice circular groove in each disk card is arranged axisymmetricly; The two panels cutting ferrule 11 be arranged symmetrically be socketed in oval rotating shaft 7 is set, every sheet cutting ferrule is its cross section of ridge tiles shape is half elliptic, be fixed with box-shaped projection 12 separately in the upper surface of every sheet cutting ferrule and lower surface, each box-shaped projection 12 is embedded in circular groove 10.The outer wall of each cutting ferrule 11 is provided with the arc rib 13 of multiple tracks protrusion, and multiple tracks arc rib 13 divides distribution along the axis direction etc. of cutting ferrule from top to bottom.In specifically arranging, forming a cross section when two panels cutting ferrule 11 is involutory is oval sleeve, its external diameter formation matched in clearance more smaller than the internal diameter of the second action bars 2.When rotating oval rotating shaft 7 and making two panels cutting ferrule open, the outer wall of two panels cutting ferrule and the inwall of the second action bars closely cooperate, the arc rib increasing friction force of cutting ferrule outer wall, thus cutting ferrule is locked in the inwall of the second action bars, be also locked in the second action bars inner chamber by oval rotating shaft, slide bar and the first action bars.
In specifically arranging; insulation property and all good senior epoxy resin of mechanical strength or glass fibre are adopted to be refined into telescopic first action bars and the second action bars mutually; and be provided with insulation protective jacket 15 in the junction of two action bars; the lower end of insulation protective jacket is fixedly connected on the outer wall of the second action bars; the upper socket of protective sleeve, on the first action bars, prevents the junction of two action bars such as dust foreign material from entering the second action bars inner chamber.
During use, portable telescopic ground operation bar can be taken out in earth brace case 14, after earth connection connecting clip 5 is connected with earth connection, after earth terminal is fixed, with insulated sling, telescopic ground operation bar is winched to operating personnel on bar by personnel below bar, on bar, the first action bars 1 clockwise direction in the second action bars 2 rotates by personnel, two panels cutting ferrule 11 will close in oval rotating shaft 7, and depart from the inwall of the second action bars 2, first action bars 1 can be slided along the second action bars 2 inwall, after first action bars 1 is all stretched out, again the first action bars 1 is counterclockwise rotated in the second action bars 2, projection 12 on two panels cutting ferrule 11 outside (radial direction along rotating shaft) under the guiding of circular groove 10 is launched, and block the inwall of the second action bars 2, first action bars 1 and the second action bars 2 inwall are locked, now, can by the hand-held insulation hand holding handle 4 of maintainer on bar, wire clamp 3 is clipped on the wire of maintenance, complete the installing of earth connection, otherwise the dismounting work of earth connection can be completed.
